EXUP systemThis model is equipped with Yamaha’s
EXUP (EXhaust Ultimate Power valve)
system. This system boosts engine
power by means of a valve that controls
exhaust flow within the exhaust cham-
ber.NOTICE

The EXUP system has been set and
extensively tested at the Yamaha
factory. Changing these settings
without sufficient technical knowl-
edge may result in poor perfor-mance of or damage to the engine.

SidestandThe sidestand is located on the left side
of the frame. Raise the sidestand or
lower it with your foot while holding the
vehicle upright.TIPThe built-in sidestand switch is part of
the ignition circuit cut-off system, which
cuts the ignition in certain situations.
(See the following section for an expla-
nation of the ignition circuit cut-off sys-tem.)
WARNING
EWA10242
The vehicle must not be ridden with
the sidestand down, or if the sides-
tand cannot be properly moved up
(or does not stay up), otherwise the
sidestand could contact the ground
and distract the operator, resulting
in a possible loss of control.
Yamaha’s ignition circuit cut-off
system has been designed to assist
the operator in fulfilling the respon-
sibility of raising the sidestand be-
fore starting off. Therefore, check
this system regularly and have a Yamaha dealer repair it if it does not
function properly.
